4 Claims. (Cl. 61-35) This invention relates to the problems of reclaiming waste land and simultaneously disposing of city refuse or garbage.

One object of this invention is to provide a 5 compact,.firm, ll for mud ats, marshes, and

low lands, utilizing for that purpose very little materials other than ordinary garbage. A further object is to accomplish in connection with the filling in of low lands, the disposing of city refuse or garbage in a sanitary manner.

I find that ordinary garbage or city refuse, because of its large content of paper materials, will, when treated in the manner hereinafter set forth, provide a substantial, solid, firm fill suitable for building-sites, roadways, parks, etc., without the necessity of utilizing any appreciable amount of earth.

My method consists of dumping the garbage collected from municipalities, which ordinarily contains in excess of fty per cent, paper material, in a layer say of three or four feet in depth, then thoroughly soaking the layer with water until the paper content becomes more or less pulp-like, then thoroughly compacting the layer, preferably with a roller, exerting a pressure of some ten to fifteen tons, until the layer is reduced in thickness to about one-half of its original thickness. layer, I prefer to employ a spiked roller, so as to break up the larger pieces contained in the garbage and which might tend to form bridges and leave voids. After compressing the layer, I apply a deposit of a thick, viscous oil, preferably an asphaltic oil or emulsion. The oil should be in heated condition, so that it will flow readily and spread and enter any crevices and depressions in the layer, and the quantity applied should be suflicient to form a coating throughout thetop of the layer of compressed garbage. The oil serves as a binder and a top dressing for the compacted layer and at the same time it kills any objectionable odors emanating from the garbage, and repels rats.

Successive layers of garbage and oil are applied in like manner, until the desired level is reached. Even without the addition of any earth, or at least any appreciable quantity, such a lling is sufficiently firm to serve all the ordinary purposes of solid earth.

On the accompanying drawing I have illustrated how the garbage ll is applied to a mud flat IIJ. Several layers of water-soaked, compressed garbage are indicated at II, I2 and I3. The oil layers are indicated at I4, and the parts below these voil layers indicated at I5 are formed by the entrance of the oil into the depressions.

left by the spiked roller. Thus the capability of the oil to serve as a binder is facilitated.

For the purpose of compressing the In and by my method, valuable land adjacent large cities, which otherwise would be not only waste land but'a nuisance, can be created, utilizing principally the refuse or garbage from the city. The garbage disposal problem is thereby solved in a manner which is entirely sanitary and profitable.

While I have described various details of my invention, yet I have done so by way of illustration and not as a limitation thereof, since changes may be made without departing from the spirit of the invention the scope of which is dened in the appended claims.

Having described my invention, what I claim and desire to secure by Letters Patent is:

l. A method of filling low lands which consists of dumping a layer of garbage containing a large percentage of paper material, soaking the layer with water, compressing the layer to about onehalf of its original thickness, applying a coating of heavy, viscous oil to the compressed layer, so as to penetrate the layer and leave aV coating thereof on top, and proceeding in the same manner with other layers until the desired level is attained.

2. 'Ihe method of filling in mud flats and the like and disposing of municipal refuse containing a large proportion of paper material, which comprises providing on said mud flats a layer of said refuse soaked withwater, compressing said layer to about one-half its thickness, covering said resulting compressed layer with a hardening oil, and repeating said series of steps a suliicient number of times to produce the desired depth of lill.

3. The method of filling in mud flats and the like and disposing of municipal refuse containing a large proportion of paper material, which comprises providing on said mud ats a substantially four-foot-thick layer of said refuse soaked with salt water, rolling said four-foot thick layer with a twelve-ton roller to a thickness of about two feet, and covering said resulting layer with hot asphaltic oil, said steps being repeated the number of times necessary to make the desired thickness of ll.

4. The method of filling in mud flats and the like and disposing of municipal refuse containing a large proportion of paper material, which comprises providing on said mud flats a layer of said refuse soaked with water, simultaneously indenting and compacting said layer to about one-half its thickness, and filling the resulting indentations and covering said resulting layer with a hardening oil, said steps being repeated the number of times necessary to make the desired thickness of ll.
